Hello,

In fifth week I implement idr - integer management library using code of
file descriptor allocators in kern_descrip.c. Worked to use the new library
to be used with filedesc, however something or other didn't work out. Will
be trying that again after looking at code more properly. Rest tested
existing work done till now which seems to work quite fine. There are
mainly two events left to handle IN_MOVED_TO and IN_MOVED_FROM, which I'm
being able to detect however have to synchronise them both using cookie
argument.

Hello,<br>
<br>
This week's status -<br>
<br>
* Added following notes for EVFILT_VNODE - NOTE_OPEN, NOTE_ACCESS,<br>
NOTE_CLOSE_WRITE, NOTE_CLOSE_NOWRITE, NOTE_CREATE. They work with Hammer<br=

and UFS.<br>
<br>
* Implemented inotify_read() and have the most important masks working.<br>
Hence now we have a working inotify system.<br>
